MACHINE FOR MAKING SHOOKS FOR BOXES.

SPECIFICATION forming part of Letters Patent N 0. 726,329, dated April 28, 1903..

Application filed May 5. 1900. $erial No. 15,611. (No model.)

T at whom it may concern:

Be it known that I, HENRY W. MORGAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines for Making Shocks for Boxes; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification,and to the reference-numerals marked thereon.

My present invention has for its object to assemble and fit together a series of matched boards or pieces forming the sides or bottoms of boxes and termed in the trade shooks;? and the invention consists in certain improved constructions and combinations of parts whereby the appropriate boards being placed in the machine are automatically fed and pressed together with their interlocking tongues and grooves in engagement in such condition that the shooks may be taken directly to the nailing-machine and formed into boxes, all as will be hereinafter fully described, the novel features being pointed out in the claims at'the end of this specification.

In the drawings, Figure 1 is a side elevation of a machine constructedinaccordance with my invention; Fig. 2, a similar view of the opposite side; Fig. 3, a plan view of the machine; Fig.4, alongitudinal sectional View; Fig. 5, a cross-sectional view taken on the line a a of Fig. 3; Fig. 6, a sectional view taken on the line b b of Fig. 1; Fig. 7, ahorizontal sectional view taken on the line 0 c of Fig. 5.

Similar reference-n u merals indicate similar parts.

The main frame of the machine may be of any suitable construction, but in the present instance consists of the side frames 1 1, connected by suitable cross-braces and also near the top by theflbed, table, or work-support 2. The sides 1 of the machine are provided with the extensionsB at the top, to which is adj ustably secureda board or fence 4, extendingl across the work-support and securedgby the bolts 5 and supported upon adjustable bolts 6, by which said fence may be elevated to infence 4 are the side plates or wings 7, adjustably secured by hand-screws 8. The fence 4 and side plates 7 constitute a receptacle whose bottom is formed by the support 2 and which is open at its forward end a space equal to the distance that the fence 4C is raised above the said bed, so that the boards from which the shook is made may be placed therein with their tongue-an .l-grooved edges in juxtaposition and the lower set or row constituting one shook may be fed from this box or container to the pressing devices. In the present instance the conveying devices for carrying the lowermost row of boards forward over the support2 consist of suitable chains 9, extending over sprockets 10 at the ends of the support and carrying at suitable intervals cross-bars or lags 11, which pass under the fence 4, as usual in machines of this description. The sprockets 10 at the feed end of the machine may be secured to orloosely mounted upon a shaft 12, and those at the forward end of the machine are rigidly secured to a shaft 13, having thereon a sprocket 14, driven by a chain from the main driving-shaft 16, on which the belt-pulleys 17 are mounted. Over the work-support or bed 2 and in rear of the fence 4 are arranged pressing or holding wheels18, mounted upon shafts l9 and adapted to hold down the boards while their matched edges are being pressed together.

the downward movement of said brackets.

The clamping or squeezing devices for forcing the matched edges of the boards into engagement embody generally two jaws or plates 25, positively moved relatively toward 'each other to squeeze them tightly into engagement. The plates or jaws are provided, preferably, with the horizontal extensions or flanges 26, extending over the end boards to hold the latter downward upon the bed, as shown particularly in Fig. 5. The

pressers are gibbed to and slide upon a suitable cross bar or frame 27, secured to the side frames of the machine, and are provided with upwardly-extended threaded lugs 28 for engaging the right and left screw-threaded rods 29 and 30, the former being connected by a pin 31 with a collar or coupling 32, to which collar is connected a rod or pitman 33 by means of a pin or pins 34, secured in-the collarand operating in the groove in the end of the pitman 33, so that while the screw will be reciprocated by themovement of said pitman it may be turned to adjust the presser 25 independently thereof. The outer end of the pitman is connected to the lever pivoted at 36 to a bracket on the side frame and having at its other end a stud or roller 37, arranged to cooperate with a, cam 38, adjustably secured to a shaft 39, mounted in bearings in the main frame and having a gear 40 thereon meshing with a pinion 41 on the shaft 13. The adjustment of the cam relatively to the gear 40, which is splined to the shaft, is effected by providing serrations on the proximate faces of the cam and gear and locking the cam in adjusted position by a hand-nut 42 on the threaded end of the shaft 39, as shown in Fig. 6, and the cam is preferably.

provided with a guard-plate 43, removably secured to the cam by means of a bolt 44, Fig. 6. The threaded rods 29 and 30 are coupled or connected at their inner proximate ends, so as to be capable of simultaneous rotation and also to permit an independent longitudinal movement, this coupling consisting in the present instance of a sleeve 45, to which one of the rods-say 29is secured by a pin 46, while the other rod 30 is provided with a spline 47, engaging a corresponding groove in the interior of the coupling-sleeve. The outer end of the rod 30 is provided with a hand-wheel 48 and also with a collar or ring 49, having its inner side abutting against the bearing-frame for the rod and engaging at its outer side a plate 50, en-

circling the rod and provided with adjustable bolts 51, extending through the outer side of a yoke or frame 52, bolted to the side frame of the machine, and between the inner side of the yoke-frame and the plate 50 are arranged springs 53, (see Fig. 7,) this construction permitting the presser-plate connected to the rod 30 to move outwardly independently against the tension of the springs 53, and the coupling between the rods 29 and 230 permits them to be rotated together to adjust the presser-plates 25 toward and from each other, as will be understood.

Just beyond the pressing devices and in the present instance at the extreme end of the machine is arranged a yielding stop for engaging the ends of the boards and holding them in alinement during the pressing operation, said stop being adapted to yield when the boards are forced through and permitting them to pass. In the present arrangement this yielding stop or alining device consists of a cross-bar 55, secured to the lower end of links 56, suspended upon a shaft 57 in bracket 58 at the side of the machine, said bar being swung toward the pressing devices by springs 59, encircling the shaft and engaging the frame and arms.

The general operation of the machine will now be readily understood.

The matched boards being placed upon the support 2 between the side plates 7 and arranged with their matched edges in juxtaposition, the machine is started, and theconveying devices will move the lower boards from the pile and beneath the fence between the pressing jaws or plates 25, said boards being yieldingly held down upon the support, and when their forward ends have engaged and been alined by the yielding stop the abrupt portion of the cam will turn the lever and force inwardly the presser-plate connected thereto toward the opposite presser plate or jaw, causing the matched edges of the boards to be firmly engaged, the springs 53 regulating the pressure. exerted and pre venting breakage of the parts. As soon as the jaws have completed their relative approach they are moved outward again by the cam and the completed shook fed forward by the continued movement of the lags 11, the alining-stop yielding and permitting their passage out of the machine. By means of the adjusting devices described the machine can readily be adapted for shooks of different widths, the clamping plates or jaws beingadjustable toward and from the center of the bed-plate or work-support. The fence can be vertically adjusted for different thick nesses of boards and the side plates 7 laterally adjusted for different widths of shooks. Instead of the feeding or conveying devices shown others could be employed.
